CAR-V-ENT'I LATO R.

SPECIFICATION forming part of Letters Patent No. 402,604, dated May 7, 1889.

- Application filed December 26, 1888. Serial No. 294,637. '(No model.)

To @ZZ whom it may concern:

Be it known that I, FRANK B. MALLORY, a citizen of the United States, residing at Flemington, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Car-Ventilators; and I do hereby declare the following to be afull, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

My invention relates to ventilator-saslies for car-windows; and it consists in a novel construction of a sliding sash having two swinging ventilator-sections provided with guards and fastenin g-bolts, the right-hand section being adapted to be opened and the lefthand one closed when the car is moving forward, and theleft-hand section'opened and the right-hand one closed when the movement of the car is reversed.

In the accompanying drawings, Figure l is a perspective view showing a portion of a palace car exteriorly and interiorly, with my ventilator applied to it. Fig. 2 is a perspective view of my improvedf sliding ventilator-sash detached. Fig. 3 is a horizontal 'section of the ventilator-sash and its guides, the ventilatorsections being adjusted for the movement of the car in the direction of the arrow l. Fig. 4 is a similar section to Fig. 3, with the ventilator-sections adjusted for the movement of the car in the direction of the arrow 2. Fig. 5 is a broken view of a ventilator-section and a vertical section through one of the guards. Fig. 6 is a broken view showing a vertical section in the line of the casing for the fastening-bolt, and Fig. 7 is a broken horizontal section of a ventilator-section through the bolt and its casing. i

My present invention, which is animprovement on the construction of the sliding ventilator-sash shown in my application for a patent allowed September 5, 1888, Serial No. 275,547, comprises a sliding frame, A, filled with a large upperA portion, A', of ,glassor other suitable analogous material, said upper portion being inclosed on all four of its sides, and below the horizontal frame-bar a, and between it and the lower frame-bar, b, it is provided with two smaller ventilator-frames, A2

\ A3, the same, respectively, being either opaque or glazed with either plain or illuminated. material, as glass or other transparent substance.

The frames A2 A3 are rabbe'ted at their free edges and at top and bottom, as shown at c, and their rabbets t like rabbets, CZ, of the sliding frame A, as' shown, and they are provided, respectively, with a hinge, f, on their inner edges, and by means of the same are vhinged to a vertical parting-bar, g, which is centrally between the frame-bars ot ando, as shown. At each of the free edges of the frames A2 A3 a sliding fastening-bolt, B, is provided, the same being arranged in a suitable casing or recess, O, of the said frames and confined by a slotted metallic face-plate, h, in the slot h of which the thumb-button h2 of the bolt plays, as illustrated. Y Y

Beneath and above the frames A2 A3 horizontal guard-plates D are applied on the outside of the sliding frame A. These plates are of V shape approximately, and on their outer side edges, respectively, a flange, i, for limiting the outward movement of frames A2 A3, is provided, one of these iianges extending down and the other upward, as shown.' Inthese guard-plates vertical bolteholes lo are provided for receiving the ends of the bolts when the ventilators are open, and in the frame-bar b notchesmand recesses 'n are provided for the passage of the lower ends of the face-plates and for the retention of the bolts when the ventilators are closed.

By constructing the sliding sash as above described a large unobstructed glazed portion, A is secured above the bar a, and below this glazed portion smaller ventilatorJ portions, either opaque or glazed with plain or illuminated material, are secured, and thus the View of the passengers is not obstructed by an opaque vertical parting-bar extending from top to bottom of the sliding sash, as in the case n of my aforesaid allowed application, and at the same time all the advantages of having two ventilator-sections on a single sliding sash are retained, these advantages being the closing of a right-hand ventilator-section and opening a leftfhand one of the same sash when the car is moving in one direction, or opening arighthand ventilator section and closing a left= hand one when the car is moving in an opposite direction, whereby sparks or cinders and dust are deliected and excluded and air allowed full freedom to enter the car.

In Fig. l of the drawings at A, I have illustrated on a car the hereinbefore-described sliding ventilator-sash, and at E another sliding sash, the latter being a modification of thc sash A. In the modication at E a long and broad glass or other transparent portion, E', is shown, and on each side of the framing of this portion a long swinging glazed or opaque ventilator-section, E2, is hinged, and provided with guard-plates and a fastening device or bolt similar to those hereinbefore described in connection with sections A2 A3. By this modication I obtain a large unobstructed transparent surface from top to bottom of the sash, through which passengers can gaze, and at the same time are secured all the advantages of having free ventilation, without the annoyance of cinders and dust, whatever may be the direction in which the car is moving, and this without raising the sash, as well as facility allowed for raising the sash when required.

Very often standard railway-cars are built with some narrow windows, as at A, and some wide ones, as at E, and it is only on account of this I prefer using the side ventilators for the wide windows and the bottom ventilators for the narrow windows.

lVhat I claim as my invention isl. A single sliding sash having a stationary glazed portion and two hinged Ventilating portions provided, respectively, with a fastening device and swinging in opposite directions, substantially as described.

2. The single sliding sash A, having a stationary upper portion, A', and two lower hinged ventilator portions, A2 A3, provided, respectively, with a guard and a fastening device and swinging in opposite directions, substantially as and for the purpose described.

In testimony whereof I hereunto aix my signature in presence of two witnesses.

FRANK B. MALLORY.
